Gilles commented on CLI-219:
----------------------------
None of the proposed workarounds really matches the look of a command-line
achievable through other languages.
Is there any technical problem that prevents applying the patch?
Also, my personal opinion is that it is doing a disservice to users to let them
forget quotes whenever they would be necessary to disambiguate between an
option including a space character and two distinct options.
Historically, the space separates the tokens of a command line. If a token
contains a space, it has to be enclosed within quotes. If this would be
enforced by [CLI], then the problem of aggregating arguments to the last option
token (of an option declared to take a variable number of arguments) would
probably disappear. But this behaviour (although correct, IMO) would not be
backward-compatible.
Consequently, the patch seems to be a good compromise.

> As hinted there, a solution might be to allow that the (single) argument of
> an "Option" (cf. "hasArg()") be split according to a user-defined regexp
> pattern. If given a split pattern, the code would convert a single-arg
> "Option" into a multiple-args one (where the arguments are the result of
> splitting the single-arg string with the pattern).
